Winter the month of sudden cardiac death: So its time to revise CPR.
New mantra for CPR: just do hands only CPR
A new US ad campaign aims to demystify cardiopulmonary resuscitation by focusing on pushing fast and hard on a patients chest rather than worrying about mouth to mouth resuscitation, of which some 45 percent of adults remain wary. Sponsored by the Ad Council and New York ad agency Gotham Inc., the campaign will reach people through various mediums, encouraging them to perform hands only CPR on victims of cardiac arrest and follows CPR guidelines from the American Heart Associations Emergency Cardiovascular Care Committee updated in 2008. In fact, there are only two steps, the ads say: call emergency number and push hard and fast in the center of the patient's chest.
Campaign 100: Just compress it
Gasping, gurgling, moaning or any other noisy breathing increases the chances for survival when someone is suffering sudden cardiac arrest. Gasping is a sign that there's still blood flow to the brain, and the person can be saved even though the heart has stopped.
The first aid involves starting compressing the chest, 100 times a minute. A Phoenix study published in Circulation, of 1,218 cases, showed better survival when abnormal breathing, gasping, was noted. After gasping one may have 4-5 minutes before the breathing stops and these 4-5 minutes are crucial.
Gasping is present in 40% of the cases of sudden cardiac arrest. After timely CPR as many as 39 percent of the gaspers will survive as against 9.4 percent of the non-gaspers. If no CPR is done 21.1 percent for gaspers and 6.7 percent of non-gaspers survive.
High salt reduces the effect of BP drugs
Not only does a high-salt diet contribute to hypertension, but it can also reduce the effectiveness of blood pressure medications. What is striking about these results is the degree of the effect, reports Dr. David A. Calhoun, a professor of medicine at the University of Alabama at Birmingham, in the July 20 online issue of Hypertension.
Diabetics advised to eat more pulses and nuts
A study presented at the World Diabetes Congress reported that a diet rich in pulses and nuts can improve glycemic control in type 2 diabetes patients to within ranges seen with pharmaceutical intervention. A meta-analyses of 41 trials demonstrated that pulses, alone or in low-GI or high-fiber diets, improve markers of longer term glycemic control in humans. According to the authors of the study, dietary pulses such as chickpeas, beans, lentils, and peas have a low glycemic index, high fiber content, high levels of amylase and resistant starches, and vegetable protein, and various other antinutrients, which may act as enzyme inhibitors. The net effect is decreased digestion and absorption of starch and consequently postprandial glycemia. Out of the 41 trials, eleven examined consumption of pulses alone, which noted an overall decrease in standardized mean difference (SMD) of 0.71 in fasting blood glucose and 0.62 in serum insulin. Nineteen trials studied consumption of pulses in low glycemic index diets and observed an SMD decrease of 0.28 in glycosylated blood proteins i.e. either hemoglobin A1c or fructosamine. SMD reductions in fasting blood glucose of 0.32 and in FBG of 0.27 were observed in 11 trials investigating pulses in high-fiber diets. Dr. Sievenpiper of St. Michael?s Hospital?s risk factor modification center, Toronto said that based on these results, a 0.48% reduction in HbA1c is expected, and this level of benefit approaches that seen with acarbose, exceeds the FDA proposed clinically meaningful threshold of 0.3%, and lies at the lower limit of efficacy of what you might expect for oral agents.
Womb transplants possible in two years
Some British scientists hope to conduct a first-ever successful womb transplant within two years from now. Data was presented at a US fertility conference. If this comes about, it would serve as the best other option possible to adoption or surrogacy for women whose wombs have been rendered functionless by diseases such as cervical tumor. The scientists carried out their latest research on rabbits and transplanted a womb using a ?vascular patch technique? that connected the major blood vessels. Out of these five rabbits, two lived upto 10 months and tests showed that the transplants were successful.
Stroke tissue damage reduced by supplemental oxygen
An Indian-origin researcher has revealed in a new study that giving supplemental oxygen during the active period of the stroke greatly reduced the death of neurons and prevented the damage that free radicals can cause to lipids that help protect those brain cells. But, she also stressed that the timing of delivery of 100 percent oxygen, either in a hyperbaric chamber or by mask, is important to achieve the benefit. The study noted that animals give oxygen supplementation while blood flow was blocked had a significantly smaller amount of tissue damage than animals who received oxygen after the blood flow was restored in the brain.
Gold finds another use ?.to detect cancer
Gold is no longer just a glittering adornment that women love to show off. Gold nanoparticles can now be used to detect prostate specific antigens (PSA) that are at much lower levels which canot be detected with existing blood tests. PSA is the leading indicator of prostate cancer. PSA levels are raised in men with prostate cancer. According to Chad Mirkin, a professor at Northwestern University and a co-author of the study, after prostate cancer is removed, the PSA levels fall to zero. But, this number is actually below what can be currently detected and not really zero. The study was published in the Proceedings of the National Academy of Sciences.
H1N1 Flu India update
With four H1N1 flu deaths reported on 22.10.09, the death toll in the country has risen to 431. The total number of people affected with the flu increased to 13,142 with 112 new cases. With 185 deaths, Maharashtra records the highest deaths in the country.

Several newer anticoagulants are under clinical development.
Recently two of them, Dabigatran etexilate/Pradaxa and Rivaroxaban/Xarelto obtained marketing authorization in Europe and Canada for the prevention of thromboembolic events following major orthopedic surgery such as total hip and knee replacement.
Many other small antithrombotic molecules including a new generation of low molecular weight heparins, are currently in different stages of clinical development.
In addition to being administered orally, the newer anticoagulant agents have a more balanced benefit/risk ratio and wider therapeutic window. They have a rapid onset of action, a predictable anticoagulant effect that does not require routine laboratory monitoring. They have minor food and drug interactions, including those with cytochrome P450 and P.gp. They are highly specific and targeted to a single coagulation factor, and could carry similar or less hemorrhagic risks compared to the older anticoagulant agents. Finally, they may be used in a broader variety of patients, especially the medically ill patients with advanced cancer, and the elderly without any dosage adjustment, regardless of the patient age, gender, body weight, or in patients with mild renal impairment. Their use in the general world will hopefully confirm the promising results of clinical trials. [Journal of Thrombosis and Thrombolysis (Oct 2009)
